MATLAB: Solving nonlinear equations using Matlab

Question

Hi,

I have a function as y=f(x1,x2…xN) which contains N unknows. This equation is pretty complex and contains integral and exponential terms. Fortunately, I also have N curves and all of them can be fitted by this function with the same N variables. So is there any way using matlab to solve this equation? Thanks!
